Alexandru Gagniuc adddf9e418 lm4f: Update examples to the new GPIO API ...

We updated the GPIO API to use the AHB bus; however the AHP aperture for
GPIO ports A through J needs to be explicitly enabled at runtime. Accessing
the AHB aperture otherwise hardfaults.

To make the examples work again, we call gpio_enable_ahb_aperture() at the
start of main().

Since we're at it, we also take out the ugly register accesses in favor
of the new gpio functions.
